[Regulation of Pseudomonas carboxydoflava growth and development by specific endogenous factors].

It was established for the first time that Pseudomonas carboxydoflava synthesizes a specific autoregulator factor (d) in the process of growth; the factor is a membrane-active compound according to the mode of its action. The regulatory action of the factor is manifested in limiting the number of the cellular population of the producing culture and in the capacity to induce the transition of vegetative cells into the resting state. The new forms are characterized by the abruptly decreased level fo metabolism, the high degree of light refraction, a peculiar ultrastructural organization, and the ability to retain viability for a long period of time.
